Arduino Mega Full 3D Printer Training Kit
CNC 3D Printer Kit RAMPS 1.4 Controller + Arduino Mega 2560 R3 + LCD 12864 + 6 Limit Switch Terminator + 5 A4988 Step Motor Driver
This list is known as the ramp short or Pololu trillion rupiah. In small costly little case. RepRap harmonizes with all electronics. The Arduimo MEGA platform has plenty of room for expansion. The stepper motor driver and the Arduino MEGA shield extruder control electronics provide modular design with easy maintenance, spare parts, update and expansion capabilities as well as tooling. In addition, some may be added to the Arduino expansion cards system.
The card is generally based on Adrian's Polo Electronic work and Tonok work. Adrian's Pololu Electronic circuit design is based on Joaz. You can review the first pin descriptions and design enhancements.
The extruder has cartesian robots and arrangements.
It was expanded to check other accessories.
Heater / MOSFET outputs and three-fan thermistor circuit.
Additional security 5A and component protection integration
Control of additional heating bearings 11A Fuse
Suitable for 5-pole progressive driver card
The pole board pin socket can be easily replaced or removed for future designs.
I2C and SPI have expanded their stitches.
All MOSFETs are fitted to the PWM pin versatility.
The servo-type connector is used to connect the end stop, motor and light emitting diodes. These connectors are gold plated, 3A rated current, very compact.
SD card to insert - now available from Kliment - Sdramps
LED light is on

3D printers use LCD control panel, ramp extension accessories. With the LCD control panel where the spooling will be performed, the 3D model copies the Gcode files to the SD card and then prints the file with the LCD control panel. This version is an upgraded version of the reprint smart controller.
Limit Switch Endstop (Limit switch terminator)
Customized high-quality connection, made of 22AWG wire, copper wire can be very thick, resistant to current 2A, 300V voltages. It has an insulation layer at a temperature range as wide as 80 degrees. Common connections of fine copper wire do not match. Retrieval is not easy, just insert the appropriate sticker, you can use the plug directly to connect the other side to the cupboard for ease of use.
Red hat connection VCC (+ ramps)
Black cable GND (- -)
Green Line connection SIGNAL (ramps s)
Tips: Normal Terms and Systems Key should be configured
Pros: Easy installation, more common styles
Disadvantages: mechanical parts are easy to wear and tear, life is short
The A4988 is a microstep motor driver with no internal transducer for easy operation. This product is available in full, half, 1/4, 1/8 and 1/16 stepping modes, activates bipolar stepping motors, has output tube capacity of 35 V and ± 2A. The A4988 includes a constant off-time current regulator, the regulator operates in slow or mixed fall modes. The key to easy implementation is the A4988 converter. The 'step' input is a microstep of a stroke motor. There are no phase charts, high frequency control lines or program complex interfaces. The A4988 interface is a very convenient interface for complex microprocessors.
When micro-steps are in operation, the A4988 automatically selects the current in the falling mode in the joinery control (Slow or Mixed). Having a constant downtime during the rapid deceleration from mixed grades, it is adjusted to the slower fall time. The audible engine control scheme causes noise motor noise reduction, step accuracy to be exceeded and power consumption to be reduced. PWM (PWM) processing power. Internal circuit protection content: hysteretic thermal shutdown, low voltage lockout (UVLO) and cross-current protection. Special power sequencing.
A4988 surface mount QFN package (ES), 5 mm x 5 mm, with an overall package height of 0.90 mm, an exposed pad for enhanced thermal dispersion. This pak is Pb (suffix-T), 100% matte tin lead blend coating.
Features and Benefits
Low RDS (Open) Output
Automatic current drop mode detection / selection
Mix slow currents with falling modes
Synchronous correction for low power distribution
Internal UVLO • Cross current protection
3.3 and 5 V compatible logic supply
